Identity & Access (SSO/CIAM)
FAQ.

What is Identity & Access (SSO/CIAM) software?

Identity & Access (SSO/CIAM) covers the tools a site can load or configure to handle this part of its stack. We detect one of the 54 identity & access (sso/ciam) tools in this category on 979,945 live sites. A detection means we found the technology on the site, which is not the same as a paid account.

What are the most popular identity & access (sso/ciam) platforms?

Across 979,945 detected sites, the most widely found identity & access (sso/ciam) tools are: Facebook Login (63.43% share, 621,585 sites), Google Sign-in (22.36% share, 219,115 sites), Duo Security (2.15% share, 21,045 sites). Others we see regularly include Linkedin Sign-in and 1Password.

Which identity & access (sso/ciam) tool has the largest market share?

Facebook Login is the most widely detected identity & access (sso/ciam) tool at 63.43% share, on 621,585 sites. The largest share of those sites belongs to various companies, and to businesses in the 1-10 employee band.

Which industries use identity & access (sso/ciam) software the most?

The industries with the most detected sites in this category are Software Development, IT Services and IT Consulting, Financial Services, Technology, Information and Internet, Hospitals and Health Care. Industry mix follows where these tools get installed, so a category carried by website builders or agency templates will lean toward the verticals those platforms serve rather than the vendor's target buyer.

Which countries have the highest adoption of identity & access (sso/ciam) tools?

We detect the most identity & access (sso/ciam) sites in United States, United Kingdom, Canada, Germany, Australia. Country here is the company's registered location in our enriched data rather than where the site is served from, so read it as a ranking of markets rather than a measure of any single one.

How do I choose the right identity & access (sso/ciam) platform?

Start from your own size, industry and primary use case rather than from share. Facebook Login, Google Sign-in and Duo Security are the three we detect most often in this category, which tells you what is common, not what fits you. Compare their integrations, pricing tiers and support commitments against the workflow you actually run, and check each vendor's own documentation for current capabilities.
